Servatius von Tongern was born in Armenia as the son of Jewish parents and died a martyr's death on 13 May 384 in Maastricht in the Netherlands. Around 340 he became Bishop of Tongern and was mentioned as a participant of several councils where he was the main opponent of the teaching of Arianism. Numerous healings and miracles are reported of him. When he preached, the Holy Spirit filled him and everyone understood him in their mother tongue.
